The Elite Pigtail Explorer #3 has a thin, flexible, curved tip, which allows it to navigate around the contours of teeth and detect abnormalities such as cavities, plaque, or calculus. The “#3” typically refers to the size or design of the explorer, which can vary to suit different types of dental examinations. This instrument is essential for thorough dental check-ups and is particularly good for exploring the interproximal areas of the teeth, where other tools might have difficulty reaching.
